What's this?

I have discovered this growing on my LR. At first I thought it was just coralline, but somehow it just seems a bit more complex. Anybody know for sure? Thanks

Well besides the dark red algae (cyanobacteria) the pink spot looks like maybe just part of the live rock, or maybe a sponge or mushroom coral.
